One of these building components is connecting beam Available online in coupled shear wall which can increase plasticity and energy absorption. In this paper 21 December 2015 Keywords nonlinear finite element model of coupled beam containing HPFRCC is analyzed and the Shear wall influence diagonal reinforcement is investigated on cracking patterns stress contours and Diagonal reinforcement hysteresis diagrams of shear wall. It was observed that diagonal reinforcements play Nonlinear finite element significant role in shear load bearing capacity of shear wall coupled with HPFRCC beam. HPFRCC 2016 Growing Science Ltd.

Introduction Conventional concretes made of Portland cement and natural grains have some shortcoming and drawbacks and hence specific concretes have been designed and innovated in recent years for reducing such problems. In concrete technology this class of concretes is called advanced concretes. Conventional concretes usually have various capillary cracks and hence due to rapid development of capillary cracks under imposed stresses tensile strength of concrete materials is often low. The use of fibers in concrete . constructing fiber concrete is an effective way in prevention of micro and
